The invention also discloses a multipolar magnetic sucking disk manufactured by adopting the method. The invention is used for manufacturing an automatic horn production line.
Description
Technical field
The present invention relates to the loudspeaker automatic producing technology, be specifically related to a kind of preparation method and sucker that is used for the multi-polar magnetic sucker of loudspeaker automatic production line.
Background technology
In the preparation of loudspeaker, it is the most initial work that magnetic returns processing, includes: the plug of the inlaying of the some glue of the some glue in the outside, magnet in the basin frame, magnet, washer, magnetic rule etc.In present most of factories, mostly adopt manual operations, because magnetic returns the processing request strictness, its quality quality is closely related with personnel's hand-manipulated experimental technology, so qualification rate can't guarantee.Secondly, owing to be manual operation, operating efficiency is not high, can't satisfy user's in enormous quantities demand.
In the prior art, factory is to the assembling of loudspeaker magnetic circuit, mostly be to finish manually, cost of labor is high high, and product fraction defective height, the workman is at assembling basin frame (magnetic conductor bowl), when magnet and washer, need to use magnetic to return rule the three is located, on production technology, three's concentricity does not guarantee, in addition, the control of glue amount is also bad, has excessive glue situation the basin frame to occur, coated face between magnet and the washer three is inhomogeneous, come off easily, the gluing variable thickness causes and causes being easy to generate the slit after the glue oven dry, thereby influences tonequality, in addition, use magnetic to return predetermined bits, also make easily and produce foul in the magnetic gap, produce defective products.
At present, the production line that can be used for the loudspeaker automated production is less, and how immature and perfect, comprises all many-sides such as its kit, control system, all needs further research, exploitation.
Summary of the invention
There to be above-mentioned deficiency in order solving in the existing loudspeaker production technology, to the objective of the invention is to, a kind of preparation method of multi-polar magnetic sucker is provided, be used for this sucker of preparation efficient, standard, be used for the loudspeaker automatic production line;
The present invention also aims to, a kind of multi-polar magnetic sucker that adopts method for preparing is provided.
The objective of the invention is to be achieved by the following technical solution:
A kind of preparation method of multi-polar magnetic sucker is characterized in that it comprises the steps:
(1) metal cylinder of preparation one soft magnetic material, its inner hollow, two ends are provided with opening up and down;
(2) the permanent magnetism cover plate of preparation one hard magnetic material, its shape, size and described cartridge openings are complementary, and can seal the opening of described cylindrical shell lower end;
(3) described permanent magnetism cover plate is carried out the subregion this multipolarization is magnetized, make and form the two poles of the earth or above magnetic field on this cover plate;
(4) cover plate is encapsulated in the lower ending opening of described cylindrical shell, cover plate and cylindrical shell make end face multi-polar magnetic sucker by the mutual adhesive of magnetic force.
A kind of multi-polar magnetic sucker that adopts the preceding method preparation is characterized in that described anchor clamps comprise the metal cylinder of a soft magnetic material, both ends open, and the permanent magnetism cover plate of a hard magnetic material, and this cover plate is provided with the two poles of the earth of symmetry or above magnetic field; The geomery of described cover plate and described metal cylinder lower ending opening are complementary, and are encapsulated in respectively on this opening; Described cylindrical shell and cover plate are pulled together by magnetic force.
The present invention is mainly used in the loudspeaker automatic production line, is used for the automatic assembling process of loudspeaker and draws accessory.Accessory can carry out translation location and do not come off in suction process at the sucker end face, when being used with other anchor clamps, can guarantee product concentricity unanimity.Method provided by the invention is simple, efficient.
The present invention is equipped with permanent multi-pole magnet by the end face at sucker, form the above magnetic field in the two poles of the earth or the two poles of the earth, utilization magnetic field magnetisation loudspeaker accessory, thereby generation magnetic attraction, each accessories (iron-clad+magnet+washer) of loudspeaker is drawn, be adsorbed on accessory on the sucker under the effect of positioning fixture, but prosposition location and not coming off, thereby realize location purpose arbitrarily, and in drawing transport process, can not produce the obscission when resembling the vacuum cup suction.
Below in conjunction with drawings and Examples, the present invention is further illustrated.
